Description
Title: Exceptional Holography
Abstract: Under certain circumstances, quantum gravity shows holographic behaviour: its degrees of freedom are captured by a quantum field theory defined in some boundary region. In cases for which one has good control over the semiclassical gravitational description, the challenge is to determine what the dual field theory is. The field theory can be partially characterised by its operator spectrum, and this can be often computed from the gravity side. In this talk, I will report on recent progress in this direction within a particular realisation of the holographic principle in terms of string theory and the anti-de Sitter/conformal field theory correspondence. I will also describe how string dualities of exceptional type play a central role in this approach.
